[1] The organization was formed from a meeting in Campos do Jordão, gathering the group that orbited around Devanir José de Carvalho and Plínio Petersen Pereira, former members of the Communist Party of Brazil Red Wing (PCdoB-AV).

Acting in a period in which other organizations of the armed left went through difficulties, MRT tried to articulate itself with other revolutionary groups, such as Ação Libertadora Nacional (ALN) and Vanguarda Popular Revolucionária (VPR), to carry out actions of expropriation, sabotage, and propaganda.

The Red Wing, which emerged as a dissidence of the Communist Party of Brazil (PCdoB), had opted for the strategy of armed struggle in 1967, and in the following year carried out expropriations, which in principle were to take place only in the urban center of São Paulo and were to be used to finance the implantation of a revolutionary focus in the rural areas, with the objective of creating the conditions for a prolonged popular war.

Some of them joined the National Liberation Action (ALN), while the others, aggregated around the leaderships of Devanir José de Carvalho and Plínio Petersen Pereira, founded the Tiradentes Revolutionary Movement (MRT).

[7] In September 1969, a meeting took place in Campos do Jordão, in the interior of São Paulo, attended by the groups aggregated around Devanir de Carvalho and Plínio Petersen, representatives of the Palmares Armed Revolutionary Vanguard (VAR-Palmares), the Communist Workers Party (POC), and the Democratic Network (REDE).

After the initial discussions, the political lines of each organization seemed to be well defined, and the militants who attended the meeting were free to make the decision they liked best, and could choose to join any of the groupings represented there.

Another expropriation together with REDE was carried out on September 8, at the Light agency, in the Belém district of São Paulo, commanded by Devanir de Carvalho and Eduardo Collen Leite.

[17] In the beginning of May 1970, another action was taken, this time against Souza Cruz cigarette company, located at Lins Vasconcelos Avenue, in an action coordinated by Eduardo Leite, for REDE; Devanir de Carvalho, Antônio Guerra, Plínio Petersen, Waldermar Andrew and José Rodrigues Ângelo Junior, for MRT; and Fernando Sanna Pinto and Jayme de Almeida for the Revolutionary Marxist Movement (MRM), organization that started to act very close to MRT.

[18] At the end of the month there was a robbery at Banco do Brasil, in Jabaquara, in which there was an intense exchange of fire that resulted in casualties between the bank security guards and an ALN militant.

Today the armed forces, instructed by the Americans, torture and kill those who fight for the Brazilian people and for the true independence of Brazil, like the worker Olavo Hansen, the student Edson Luís, Father Henrique Pereira, Sergeant Manoel Raimundo Soares, the patriot Carlos Marighella.

In the vote, in conversation or in shouting, it will not happen.Still in September, MRT participated in another action of the front, which produced a financial result smaller only than the assault on Adhemar de Barros' safe.

When Lamarca left Vale do Ribeira, in the region of Registro, in the south of the state of São Paulo, where the VPR was setting up a guerrilla training scheme that was discovered by the repression, he was promptly received by the MRT leader Devanir de Carvalho.

[25] At the end of November, Lamarca was escorted by MRT cars towards the capital of Rio de Janeiro, where he was to command the kidnapping of the Swiss ambassador Giovanni Enrico Bucher.

[24] Another action was carried out by MRT together with ALN, this time an assault on the van of Andrade Arnoud Bank, on Lavapés Street, in São Paulo, in which checks, a rifle and two revolvers were expropriated.

Most of the militants who participated in this action were from the MRT: Antônio Guerra, Devanir de Carvalho, Dimas Casemiro, Gilberto Faria Lima and José Rodrigues Ângelo Junior.

[27] In February the MRT took part in an expropriation carried out in Metalúrgica Mangels, then on Presidente Wilson Avenue, in the capital city of São Paulo, yielding around 270 thousand Brazilian cruzeiros and armaments belonging to the site's security.

On the 30th, on the eve of the seventh anniversary of the military coup of 1964, the front tried to carry out a sabotage action, whose objective was to blow up the Jaguaré Bridge, over the Pinheiros River, in the São Paulo capital.

The idea of kidnapping Nobuo Okushi was initially suggested in a joking tone, when the VPR militant José Raimundo da Costa proposed to exchange "one Japanese for another".

However, militants from the Revolutionary Brazilian Communist Party (PCBR) were arrested in the Northeast, making any action in that region impossible, and shortly before, Joaquim Câmara Ferreira, the ANL leader who had taken Marighella's place, was killed by repression.

[43] In a confidential DOPS document, it is stated that during the interrogation of Waldemar on February 7, 1971, it was revealed that one of the individuals closest to Devanir de Carvalho was a militant known as "Márcio", whose identity was not yet known.

However, Waldemar provided information that made it possible to identify "Márcio", and the repression learned that this militant was a bank clerk from the countryside, and that he had obtained his driver's license between September 1970 and February 1971.

[47][48] In reprisal, on April 15, a joint command of the MRT and the ALN murdered businessman Henning Albert Boilesen, president of Ultra company and an active collaborator of the DOI-CODI.

[49] Dimas Casemiro, Gilberto Faria Lima and Joaquim Alencar Seixas, of the MRT, and Carlos Eugênio Paz, José Milton Barbosa and Iuri Xavier Pereira, of the ALN, participated in the action.

The document, signed by Gilberto Faria Lima and Dimas Casemiro, was marked by a study of the beginning of the Brazilian military dictatorship and the armed struggle initiated by leftist organizations.

Besides characterizing the dictatorship then in force as fascist, it reaffirmed the conviction in the conception of the prolonged popular war, revealing the influence that Maoism constituted on the organization, even though observing that the way to build such a goal had to be with the use of fighting techniques far from those advocated by the Chinese.

This document was approved by the MRT command and became the official political line of the organization, so that its actions became focused on urban guerrilla warfare, and the objective of establishing itself in the countryside was left in second place.

The last two armed actions of the group, such as the attempt to blow up the Jaguaré Bridge and the assassination of Henning Boilesen, exemplified such methodology that prioritized sabotage and attacks against the economic bases of the regime.

In later meetings, Devanir would have perceived that Plinio was "taking possession" of the actual command of the organization, since everything that he proposed was supported by Waldemar, determining the majority of votes and, consequently, the acceptance of the decisions.

The second, called the "Yoshitane Fujimori Base" consisted of Casemiro, its coordinator, Gilberto Faria Lima, José Rodrigues Ângelo Júnior and Ivan Seixas.

In this sense, the MRT's familiar "apparatuses" were fundamental in assisting militants articulated on the armed front, allowing a façade upon which the organizations could act with a certain amount of security and freedom.
